gevent-cooperative child processes and inter-process communication.
From 2012 to 2018 gipc’s home was at bitbucket.org/jgehrcke/gipc. Since 2018 development continues on GitHub.
gipc (pronunciation as in “gipsy”) provides reliable child process management and non-blocking inter-process communication in the context of gevent.
Direct usage of Python’s multiprocessing package in the context of a gevent-powered application is error-prone and may break the application in various subtle ways . With gipc, multiprocessing.Process-based child processes can safely be created anywhere within your gevent-powered application. The API of multiprocessing.Process objects is provided in a gevent-cooperative fashion. Also, gipc provides a pipe-based transport layer for gevent-cooperative inter-greenlet and inter-process communication. gipc is lightweight and easy to integrate.

The current version of gipc works on CPython 2.7/3.4/3.5/3.6/3.7. It requires gevent 1.2 or 1.3 and supports both, Unix-like systems as well as Windows. On Unix-like systems, gipc also works with PyPy2.7 and PyPy3. gipc’s test suite is automatically executed on Linux, Darwin (macOS), and Windows.
